MFBM1V1005-801-R

Overview

The MFBM1V1005-801-R is a multilayer ferrite chip bead designed for EMI suppression in power line applications. Manufactured by Eaton Electronics Division, this component features a single-line configuration housed in a compact 0402 (1005 metric) surface-mount package with dimensions of 1.00mm x 0.50mm and a maximum height of 0.65mm. It provides an impedance of 800 Ohms at 100 MHz with a tolerance of ±25%. The device supports a maximum DC current of 300mA and exhibits a maximum DC resistance of 650 milliohms. It operates within a temperature range of -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Multilayer construction for effective electromagnetic interference suppression
• Single-line design optimized for power line filtering applications
• Compact 0402 footprint suitable for space-constrained surface-mount layouts

Applications

• Power line noise suppression in portable electronic devices
• EMI filtering in mobile communication equipment
• Signal integrity management in consumer electronics

Procurement Notes

Verify the specific impedance value and current rating against the official Eaton datasheet before integration. Confirm that the 0402 package dimensions align with your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Check for RoHS3 compliance if required by your manufacturing standards. Validate the supplier's authenticity to avoid counterfeit components.

Selection Notes

Select this component when high impedance at 100 MHz is required for a single power line in a small form factor. The 300mA current rating suits low-power circuits. Consider the 650 milliohm DC resistance impact on voltage drop. Compare with other MFBM1V series variants if higher current handling or different impedance characteristics are needed. Ensure the surface-mount technology matches your assembly capabilities.

Part Context

This part belongs to the MFBM1V series of multilayer ferrite chip beads from Eaton Electronics Division. The series offers various impedance values and current ratings in standard metric packages. These components are engineered for EMI suppression in modern electronic systems where space is limited. The MFBM1V1005-801-R specifically targets applications requiring 800 Ohms impedance in a 0402 case size.

Replacement Considerations

Direct substitutes include other MFBM1V1005 variants with similar impedance, such as MFBM1V1005-800-R (80 Ohms) or MFBM1V1005-102-R (1000 Ohms), provided the impedance difference is acceptable. Verify current ratings and DC resistance for any cross-replacement to ensure circuit performance remains unaffected.
